I am up to the stage of installing the electronic internals of the sub and I see that Engel say to remove all electronic components prior to gluing the middle deck (AKA, the wtc cover) in position.Can someone explain why this is required.

Giovanni, Thanks for your quick reply. I thought this may have been the case but the adhesive I am using is "Great Planes" 90min epoxy resin and have been using this for years on my aircraft and train models with no effects on any circuits.Maybe I've been lucky but I will heed your advice and not re-install any gear for 24 hours ( stated curing time), after application, as this will be a fairly heavy application around the middle deck.Once again thanks Peter Webster

The two types of glues I have are Great Planes , as previously mentioned, and "Bob Smith Industries" glue, both 30min. to 90min. setting time. I am mainly wanting to use these to glue support plates for things such as the radio gear, lead ballast, dive tubes and allied switch circuits. I have looked on both bottles and there is no mention of what type of glue it is. I guess you learn as you go along.Can any Aussie members assist in telling me where I can get some polyester adhesive. I will buy it from overseas if need be.Sorry to be a pest but I just want to get it rightPeter Webster

Me again guys, After having another a more thorough read of the building instruction book I see that Engel mention that you can use either epoxy or polyester resins on all but the installation of the middle deck i.e. the water tight section.To glue this they state that this "should be glued in with the Polyester Laminating Resin" and advising that it should be thickened using micro-balloons.I have found this laminating resin at our local Paint Stop store, so it looks like this problem is solved but no doubt there will be many more to come so I will just have to, as my Dad use to say, make haste slowly.Thanks for everyone's help.Peter Webster
